v4.6.8

With this version it is now possible to ask PDFWriter to generate an Xref table using PDF 1.5 Xref streams, instead of a default method of writing Xref table. This allows creating PDF files that are larger than 10gbs, a limitation created by how default xref tables are written.

To use this feature provide true as the value of a new parameter in PDFCreationSettings, as in the following example:

EStatusCode status = pdfWriter.StartPDF(
    "./myfile.pdf",
    ePDFVersion15,
    LogConfiguration::DefaultLogConfiguration(),
    PDFCreationSettings(
        true,
        true,
        EncryptionOptions::DefaultEncryptionOptions(), 
        // use true as the 4th parameter value to set WriteXrefAsXrefStream 
        // and generate xref table as xref stream
        true
    )
);

Make sure to set the version to one that's higher or equal to PDF1.5 on your PDFs to mark to readers that you are using this feature (or other 1.5 or higher features).

This release is the first one to drop PDFWriterTesting from the archived package. This reduces the download size from around ~100mb to 3mb, which is not bad for a day of work.
Thanks for a very good proposal @darcy-shen :).

Full Changelog: v4.6...v4.6.1

v4.6

In this release:

• XMake support. The project now includes the required lua file to make it an official xmake package. Thanks @darcy-shen for his contribution.
• Bundled Tiff library upgrade. Bundled tiff lib is upgraded to 4.6 (matching hummus version is unintentional haha). This might break your code if you have been using the bundled tiff code directly, which good chances you didn't and so nothing to worry about. I hope the upgrade process is not going to be too difficult. In the project it was just a matter of few type updates. The upgrade happened as part of the discussion in #226 to avoid a future deprecation of the basic types used in libtiff. Hope its not gonna inconvenience you.

What's Changed

• Add xmake build definition and enable ci by @darcy-shen in #228
• feat: upgrade bundled libtiff to 4.6 by @galkahana in #227
